PI3K — Glycine max

Summary

GmPI3K (GLYMA_04G094500V4) encodes a phosphatidylinositol 3-kinase (PI3K) of the class III/VPS34 type, possessing protein serine/threonine kinase activity, ATP binding, and protein complex binding. This soybean gene on chromosome 4 is associated with phosphatidylinositol 3-phosphate biosynthesis, pexophagy, downregulation of macroautophagy, and glycolipid metabolism. It has been linked to salt stress response, proline accumulation, leaf senescence, pollen germination and development, root hair growth, heat stress recovery, and cellular homeostasis. The encoded protein localises to the phosphatidylinositol 3-kinase complex class III, endosome membrane, Golgi complex, and TOR complex. Studies of related genes in other species connect the family to plant growth and development, disease resistance, stomatal closure, and abnormal pollen development.
